An abandoned school building in Newark, New Jersey, suddenly went up in flames late Monday, and firefighters were still working to douse hotspots six hours later.
The cause of the blaze at the old Bergen Street School is under investigation; no injuries were reported.
The fire broke out at the school, which has been shuttered since 2010, around 11:45 p.m. Monday. Hours later, while a fire truck was at the scene, the fire reignited in the cockloft area and was elevated to three alarms, officials said.
EMS treated a firefighter at the scene for a cut to the forehead and the firefighter remained on duty. The fire was under control shortly before 6 a.m.
Video from the scene shows fire shooting out of the roof of the building and thick smoke rising into the air.
The area around the fire was very smoky, but no nearby homes or buildings had to be evacuated.
